SPECIFICATION forming part of Letters Patent No. 267,576, dated November14, 1882.

Application filed September 20, 1882. (No model.)

To all whom it may concern:

Beit known that I, THOMAS OBRIEN, a citizen of the United States,residing at Maiden Rock, in the county of Pierce and State of Wiscousin,have invented certain new and useful Improvements in Bed-Springs; and Ido declare the following to be a full, clear, and eX- act description ofthe invention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to the letters and figures of referencemarked thereon, which form a part of this specification.

My invention relates to that class of bedsprings known as twin springs,the object being to so arrange springs of this character that a pairofsuch springs will act in unison to brace and re-enforce each other onpressure being brought upon them.

The invention consists in the construction and arrangement hereinafterdescribed; and, iurther, the invention consists in the means forattaching the springs to their respective slats.

In the drawings, Figure I is a perspective view, showing a pair of twinsprings arranged in accordance with my invention. Fig. 2 is an end viewof the same, showing the manner of connecting the springs to theslat'sections; and Fig. 3 is a side view, showing the manner ofattaching the spring to the slat.

A A represent two slat-sections, and B B BB a pair of twin springssecured thereto and in close proximity one to the other, one side of theupper coils a a of the springs B B resting on one side of the uppercoils c c of the spring B I3. The lower coil, b b b, b', of each springrests upon the slat and terminates in hook G, which is bent to embracethe sides and bottoms of the slats.

The lower coils b b may project from the upper face of the slat, and theterminal ends c of the angular hooks are passed or forced between theslat and coil., as shown in Figs. l

and 3.

The connecting-wires D D, formed integrally with each pair of twinsprings, are bent inwardly toward each other, as shown, to form acentral platform, E, on the same plane as the outer sides of the uppercoils a a', to receive weight or stra-in bearing centrally on thesprings.

It will be seen from the foregoing that when weight is brought to bearupon the outer side of the upper coils` they more inward, thus bracingand re-enforcing each other. The central platforms, E, formed by thebent connections D D, being upon the same plane as the outer sides ofthe links, receive all strain brought to bear centrally on the springs.

It will also be obvious that by forming the angular hooks C to embracethe sides and bottoms of the slats, as set forth, all boring orrecessing of said slats is rendered unnecessary and the use of auxiliarysecuring devices dispensed with.

What I claim as new, and desire to secure by Letters Patent, is-

l. The combination, in a bed-bottoni, of a pair of twin springsconsisting of the coils B B, connecting-wires D D, and hooks O O, saidsprings being so arranged on the slats of the hed that their upper coilswill overlap each other, while their lower coils will rest upon andproject beyond the edge of the slat, to receive the upwardly-bent end ofthe hook O, substantially as set forth.

2. The combination, in a bed-bottom, ofthe springs B B', having theirlower coils bearing on the slats and projecting therefrom andterminating in angular hooks C O, which embrace the sides and bottoms ofthe slats, and are passed through the projecting portions of the lowercoils ot the springs, to hold the ends of thehooks between the coils andthe slats, as set forth.

In testimony whereof' I affix my signature in presence of two witnesses.

THOMAS OBRIEN.
